La présente invention concerne un rotor destiné à une éolienne qui empêche les aimants permanents de se séparer du rotor du fait de la fusion de parties des aimants permanents collées au rotor par une atmosphère à haute température sans intégrer les aimants permanents dans le rotor. Le rotor comprend un corps circulaire comportant des rainures de forme trapézoïdale, formées horizontalement dans la surface circonférentielle externe du corps circulaire et espacées à intervalles réguliers, la partie centrale du corps circulaire étant reliée à un axe rotatif, les aimants permanents ayant une forme trapézoïdale et étant insérés horizontalement et de manière amovible dans les rainures; et des anneaux de fixation installés de manière amovible respectivement sur les surfaces avant et arrière du corps circulaire de manière à être intimement fixés aux surfaces avant et arrière des aimants permanents pour retenir et fixer lesdits aimants permanents.
